Abstract Objective . Spinal stimulation is a promising method for restoring the function of paralyzed limbs following neurological damage to descending pathways. The present study examined forelimb movements and muscle responses evoked by subdural spinal cervical cord in sedated monkeys or during an arm-reaching task. Approach We chronically implanted platinum electrode array with eight channels over dorsal-lateral aspect enlargement. electrodes had diameter 1 mm inter-electrode...

This paper proposes a recommendation method of alternative-ingredients based on co-occurrence relation recipe database. Currently, dishes are often cooked with reference to recipes Website. Convenience access so many and varied encourages beginners cook. Recipe Website list ingredients used for dish. However, some reason, the listed cannot be cooking; this defines such ingredient as "exchange-ingredient." To cook dish, it should alternate exchange-ingredient another one (i.e.,...

The Innovators Market Game (IMG) has been proposed as a tool for aiding innovative thoughts and communication, coming after our 10-year experiences in chance discovery where tools of data visualization have applied cases decision making business teams. This game enabled to run accelerate the process innovation, well train human's talent analogical combinatorial thinking. In this paper, we compare effects IMG table Web based environment communication fundamental features are imported. these...

The purpose of this study is to visualize speech nuance using speech-balloon shapes in textbased communication. Though disappears a text communication, comic readers can recognize from the shape, which expresses nuances, emotions, and intentions. Through subjective evaluation experiments, we confirmed that changed emotion towards phrases. In paper, focus on relationships between linguistic features speechballoon shapes, developed an estimation model for with Naive Bayes classifier....

Optical properties of conducting polymers with Si atoms in main chains, such as optical absorption, photoluminescence (PL), and electroluminescence (EL), have been studied. The electronic energy structures determined by electrochemical measurements. strong PL high quantum efficiency has clarified, spectral narrowing observed pulse excitation a nitrogen laser. Intense blue or red EL also demonstrated the emission improved anode surface modification annealing.

In the past few years, supplying value-added and innovative products has become an important business strategy. this paper, a system method of knowledge elicitation based on chance discovery for new product design is proposed described. This contains three functional modules: (1) scenario graph generation module by using Keygraph, visual tool discovery; (2) solicitation innovators market game (IMG), kind table collaborative innovation; (3) alternatives selection analytic hierarchy process...

We compared and analyzed eye tracking experiments to test the hypothesis that patterns generated during picture viewing were mainly determined by movement links. Eye data collected from participants who viewed photographs of artistic portraits an active viewing. The links as a popular evolutionary computational model, based on Genetic Algorithm, did not anticipate saccade sequences movements. optimized Algorithm (GA)-generated graphs differed considerably tracking. existing evidence is...

In this challenge, we develop and distribute an integrated environment to flexibly combine multiple text mining techniques. Text techniques include numerous tasks such as salient sentence extraction, keyword topic textual coherence evaluation, multi-document summarization, clustering. Although tools that individually perform one or more of the above-mentioned exist, it is difficult integrate activate for a particular task. We attempt provide flexibility exist in community our proposed...

Optical properties of conducting polymers with Sn atoms in main chains, such as optical absorption, photoluminescence (PL), and electroluminescence, have been studied. The electronic energy structures determined by electrochemical measurements. Strong PL high quantum efficiency has clarified the films, photopumped multimode laser emission was demonstrated from cylindrical microcavities formed these coated around fibers.

The "value" in this paper can be dealt with as a new variable which business workers create from their interaction the dynamic environment, on they redesign products and market sustainably. Here we first show how data mining visualization provide useful tools for aiding marketerspsila/designerspsila sensitivity of emerging values consumers/users. By visualizing data, human find relations between existing entities, combination via found relations. Then Innovation Game is introduced an...

We have developed a table game named Innovation Game that supports users in thinking up ideas by combining existing products. There are two kinds of players the Game, innovators and investors. While think propose them, investors criticize make decisions whether they invest money to or not. In do not only ideas, but also improve reflecting comments from represent negative impression ideas. Although it has been considered invested much might be related investors, relation validated. analyzed...

Tsugology is the science and technology for dealing with tsugoes, where a Tsugo set composed of an intention working/living human constraints which may restrict way to achieve or other/others' intentions. The incomplete expression by each subject about his/her tsugoes sometimes cause inefficient communications, force restarting project because latent conflicts get externalized on way. In Tsugology, we study format human, process finding conflict solutions creating business opportunities both...

This paper proposes a method to estimate group of featured characters during an arbitrary period in comics. Comics have so many aspects attractiveness such as illustrations and quotes. The storyline, which is one the attractive comics, enables us enjoy dramas In story driven by characters' activities represented multimedia forms: emotion, speech, some other actions. paper, first step recognize tackles estimation given period. To compute storyline comics with facility, proposed uses sequence...
